Monga alloy premium aerospace-grade alloy,2019 pepala la aluminiyamu(yomwe nthawi zambiri imatchedwa alloy 2019) imadziwika chifukwa cha makina ake apadera komanso ntchito zapadera. Bukuli likuyang'ana momwe amagwiritsidwira ntchito m'mafakitale, mawonekedwe aukadaulo, ndi zinthu zofunika kusankha, kupatsa mphamvu ogula kupanga zisankho zabwino pakugula.

1. Makhalidwe Odziwika a 2019 Aluminium Sheet

(1) Chemical Composition & Alloy Structure

- Zinthu zoyambira: 4.0-5.0% mkuwa (Cu), 0.2-0.4% manganese (Mn), 0.2-0.8% silicon (Si), aluminium moyenera (Al).

- Kupsa mtima kotha kutentha (mwachitsanzo, T6, T8) kuti mukhale ndi mphamvu zowongoleredwa kudzera pakuwumitsa mvula.

(2) Katundu Wamakina

- Kulimba kwamphamvu: Kufikira 480 MPa (kupsa mtima kwa T8), kupitilira ma aloyi ambiri a 6000 ndi 7000 pazogwiritsa ntchito zina.

- Mphamvu zokolola: ~ 415 MPa (T8), kuwonetsetsa kuti kusinthika pang'ono kukulemedwa.

- Elongation: 8-12%, kugwirizanitsa brittleness ndi mawonekedwe.

(3) Processability & Corrosion Resistance

- Machining: Kupanga bwino kwa chip mu CNC mphero ndi kutembenuka, ngakhale mafuta amalimbikitsidwa kuti azigwira ntchito mwachangu.

- Weldability: Wapakati; Kuwotcherera kwa TIG kumakondedwa kuposa MIG pakupanga kukhulupirika.

- Kulimbana ndi dzimbiri: Kuposa 2024 alloy mumlengalenga, ngakhale chithandizo chapamtunda (anodizing kapena penti) chimalangizidwa m'malo am'madzi.

(4) Thermal & Electrical Properties

- Thermal conductivity: 121 W/m·K, yoyenera zigawo zoziziritsira kutentha.

- Mayendedwe amagetsi: 30% IACS, yotsika kuposa aluminiyamu yoyera koma yokwanira kugwiritsa ntchito osagwiritsa ntchito ma conductive.

2. Mapulogalamu Oyamba a 2019 Aluminium Sheet

(1) Makampani Azamlengalenga: Zida Zapangidwe

2019 alloy, yomwe idapangidwira ma fuselages a ndege ndi mapiko, imapambana m'malo opsinjika kwambiri. Kukana kwake kutopa kwambiri komanso kulemera kwa mphamvu kumapangitsa kuti ikhale yabwino kwa:

- Mitu ya ndege, zolumikizira, ndi zida zotera

- Zovala zamagalimoto za rocket ndi zida zamlengalenga

- Zigawo zotentha kwambiri mu injini za jet (mpaka 120 ° C), chifukwa cha kukhazikika kwake kwamafuta.

(2) Chitetezo ndi Zida Zankhondo

Kukaniza kwa alloy ku zotsatira za ballistic ndi dzimbiri m'malo ovuta kumayenerera:

- Mapanelo amagalimoto okhala ndi zida komanso chitetezo choteteza

- Zovala zoponya mizinga ndi nyumba zamakina zamakina ankhondo.

(3) Zida Zagalimoto Zapamwamba

M'galimoto zamagalimoto ndi magalimoto apamwamba,2019 aluminium yowonjezeradurability popanda kusokoneza kulemera:

- Zida zamagalimoto othamanga ndi magawo oyimitsidwa

- Mabulaketi amphamvu kwambiri a injini ndi nyumba zotumizira.

(4) Makina Olondola ndi Zida

Kukhazikika kwake ndi kukhazikika kwake kumapangitsa kuti ikhale yoyenera:

- Jigs, zosintha, ndi nkhungu mu CNC Machining

- Zoyezera zamamlengalenga ndi zida zoyezera.

3. Momwe Mungasankhire Mapepala Aaluminiyamu Apamwamba 2019

(1) Tsimikizirani Chitsimikizo cha Alloy & Traceability

- Pemphani ziphaso zoyezetsa mphero (MTCs) zotsimikizira kapangidwe ka mankhwala ndi makina.

- Onetsetsani kuti zikutsatira miyezo yapadziko lonse lapansi: ASTM B209, AMS 4042 (mlengalenga), kapena EN AW-2019.

(2) Unikani Kutentha & Magwiridwe Amakina

- Kupsa mtima kwa T6: Mphamvu yayikulu yokhala ndi ductility yocheperako (yoyenera mayendedwe osasunthika).

- Kupsa mtima kwa T8: Kulimbitsa kukana kwa dzimbiri kupsinjika, koyenera pazinthu zomwe zimapakidwa mozungulira.

-Tchulani mayeso olimba komanso kuuma (mwachitsanzo, sikelo ya Rockwell B) kuti mutsimikizire magwiridwe antchito.

(3) Yang'anani Ubwino Wapamwamba & Kulekerera Kwamawonekedwe

- Mapeto apamtunda: Yang'anani zokala, zodzigudubuza, kapena makutidwe ndi okosijeni, mapepala amlengalenga amafunikira Class A pamwamba.

- Kulekerera makulidwe: Tsatirani miyezo ya ASTM B209 (mwachitsanzo, ± 0.05 mm kwa mapepala a 2-3 mm).

- Kukhazikika: Onetsetsani kuti uta ndi camber sizidutsa 0.5 mm/m kuti mugwiritse ntchito molondola.

(4) Unikani Mphamvu Zopereka

- Njira zopangira: Kukonda ogulitsa omwe ali ndi zida zotenthetsera ndi zotenthetsera kuti zikhale zabwino kwambiri.

- Kusintha Mwamakonda: Yang'anani omwe amapereka chithandizo chodula mpaka kukula ndi chithandizo chapamwamba (anodizing, zokutira).

- Kuwongolera Kwabwino: Zitsimikizo ngati ISO 9001 kapena AS9100 (zamlengalenga) zimawonetsa ma protocol oyesa molimba.

4. 2019 Aluminium vs. Competing Alloys

- 2019 vs 2024 aluminiyamu:2019 imapereka kutentha kwabwinokomphamvu ndi kachulukidwe kochepa, pomwe 2024 ili ndi ductility yapamwamba. Sankhani 2019 pazinthu zamlengalenga zomwe zimafuna kukhazikika kwa kutentha.

- 2019 vs 7075 aluminiyamu: 7075 ili ndi mphamvu zapamwamba koma kusauka kwa makina, 2019 imakondedwa ndi magawo ovuta amlengalenga.

Kuphatikizika kwapadera kwa pepala la aluminiyamu la 2019 lamphamvu kwambiri, kukhazikika kwamafuta, ndi makina osinthika amaziyika ngati mwala wapangodya muzamlengalenga, chitetezo, komanso kupanga mwatsatanetsatane. Posankha alloy iyi, ikani patsogolo chiphaso, kuyenerana ndi mkwiyo, ndi ukadaulo wa ogulitsa kuti muwonetsetse kuti zikuyenda bwino. Kuti mupeze mayankho okhazikika kapena maoda ambiri, funsani gulu lathu - lodziwika bwino popereka aluminiyamu ya kalasi ya 2019 yokhala ndi satifiketi yotsimikizika ya mphero komanso luso la makina olondola.
